Abstract

This thesis consists essentially of two distinct parts. The first part deals with the development of the theory and the second part deals with experimental verification of the theory.

The theory developed in this paper applies to the analysis of prismatic shells, also called hipped-plate structures or "Faltwerke", and uses only techniques commonly employed in structural engineering analysis. A cylindrical shell is approximated by a prismatic shell and analysed as such. In the analysis, extensive use is made of a relaxation or distribution method. Both simply supported and continuous shells are treated.

For the purpose of verifying the theory several test models were built, both prismatic and cylindrical. Stresses were measured with electric strain gages, and close agreement was found between theory and experiments.
